Question

I want to sort a DataGridView by a column when the form loading, but I got an exception.

    private void frm_Load(object sender, EventArgs e)
    {
        // TODO: This line of code loads data into the 'dataSetExclusion.Exclude' table. You can move, or remove it, as needed.
        this.excludeTableAdapter.Fill(this.dataSetExclusion.Exclude);
        this.dgv.Sort(this.dgv.Columns["ID"], ListSortDirection.Ascending); 
    }

The column’s headtext in the DataGridView dgv is “ID”. Its DataPropertyName is “ExcludeID”. I tried both “ID” and “ExcludeID” for the column name, but still got the exception.

Value cannot be null.Parameter name: dataGridViewColumn
